What It Would Mean for Europe if They Can No Longer Rely on the United States for Military Support

At the Munich Security Conference on February 14, 2025, U.S. Vice President J.D. Vance delivered a provocative speech that has significantly impacted transatlantic relations. He criticized Europe's internal challenges, including issues like uncontrolled migration and social media censorship, suggesting that these pose greater threats to European democracy than external actors such as Russia and China. Vance's remarks have been met with strong disapproval from European leaders, including German Chancellor Olaf Scholz and Defense Minister Boris Pistorius, who have rejected his criticism.

In response to these developments, Ukrainian President Volodymyr Zelenskyy emphasized the critical importance of U.S. support for Ukraine. He expressed concerns about potential shifts in U.S. foreign policy, particularly regarding efforts to end the war, stating that without U.S. aid, Ukraine's survival would be very difficult. Zelenskyy also called for the creation of a European army to bolster Ukraine's defenses amidst Russia's

These events underscore the evolving dynamics in transatlantic relations and the challenges Europe faces in ensuring its security and democratic values amid shifting U.S. foreign policy.

For decades, Europe has benefited from the military support of the United States, with the North Atlantic Treaty Organization (NATO) serving as a cornerstone of transatlantic security. The U.S. military presence on the European continent, combined with its technological superiority and nuclear capabilities, has been crucial in deterring threats, particularly from Russia. However, what if this longstanding alliance were to crumble? What would happen if Europe could no longer rely on U.S. military power?

This question has gained increasing importance in recent years as geopolitical tensions rise and the political climate in the U.S. shifts. With debates over U.S. foreign policy priorities, national security spending, and international alliances, Europe may need to start thinking seriously about a future where it is on its own for defense. If Europe were to lose the safety net of American military support, the continent would face a multitude of challenges across defense, diplomacy, and economic stability.

1. Weakened Security and Increased Vulnerability

One of the most immediate consequences of Europe losing the U.S. military umbrella would be the sharp decline in its overall security. The U.S. military, with its advanced capabilities and global reach, has been instrumental in maintaining peace and stability in Europe. This includes deterring Russian aggression, especially in the Baltic states and Eastern Europe, as well as responding to crises in the Middle East, North Africa, and elsewhere.

Without the U.S., NATO would be left relying primarily on European forces, which, while capable, lack the scale and technological edge of the U.S. military. While countries like the U.K., France, and Germany have substantial military forces, they do not have the resources to provide a full-spectrum defense against major powers like Russia or a terrorist threat on the scale of previous U.S. engagements in the Middle East.

A Rising Threat from Russia

If the U.S. were to withdraw or dramatically reduce its military presence in Europe, Russia would likely see this as an opportunity to reassert its influence over neighboring countries, particularly those in Eastern Europe and the Balkans. This could lead to a renewed destabilization of the region, with possible territorial ambitions in former Soviet territories or NATO-member states like the Baltics.

The absence of U.S. support would also diminish the deterrent effect that NATO currently has, making it easier for aggressive actors to challenge European sovereignty. In the worst-case scenario, Russia might feel emboldened to act more aggressively, either through direct military intervention or through covert actions like cyberattacks, disinformation campaigns, or support for separatist movements.

2. The Necessity for European Military Autonomy

If European nations were forced to take on greater responsibility for their own defense, the need for a more autonomous European defense strategy would become crucial. The European Union (EU) and individual European countries would have to invest significantly in military capabilities, intelligence sharing, and defense infrastructure to ensure that they could counter external threats without relying on the U.S.

This could take several forms:

• Enhanced Defense Cooperation within the EU: The EU would likely need to ramp up its Common Security and Defence Policy (CSDP) to better coordinate military action and share resources. The creation of a more robust European Defense Union could also become a priority, with the goal of pooling resources and expertise to form a more integrated defense strategy.

• The Need for European Military Integration: There have been discussions about creating a "European Army" for years, but with the loss of U.S. support, this idea would likely gain more traction. European countries would have to integrate their forces more efficiently, standardize training, and develop joint capabilities to create a force capable of defending the continent.

  
  

However, establishing a truly independent and unified European military force would take time and require substantial investment from EU member states, many of which currently allocate a small percentage of their GDP to defense. Countries like Germany and France would need to significantly increase defense spending to make up for the loss of U.S. support.

3. Economic and Political Repercussions

The absence of U.S. military support could also have profound economic and political effects on Europe. Historically, the U.S. presence in Europe has not only provided security but also facilitated economic stability. A peaceful Europe has been a crucial partner in global trade, and the EU has benefited from the security offered by NATO and U.S. military power, ensuring safe shipping lanes, stable borders, and a reliable business environment.

However, if Europe became less secure, it could result in several adverse consequences:

• Increased Military Spending: European countries would need to spend more on defense, potentially diverting funds from social programs, education, and infrastructure. Higher defense budgets could lead to economic strain, particularly for smaller or less economically robust nations.

• Economic Instability: The uncertainty of a Europe without U.S. military backing could lead to market volatility. Investors may pull back from European markets, fearing the unpredictability of security situations. Trade agreements and investment in infrastructure could also slow down as economic uncertainty takes hold.

• Political Divisions: A Europe without U.S. support might lead to further divisions within the continent. Countries with strong defense industries, like France and the U.K., may push for a more militarized European Union, while other nations may prefer diplomatic solutions and peace-building efforts. These differences could result in fragmented political responses to external threats.

• Impact on NATO: NATO, historically a military alliance founded on the principle of collective defense (Article 5), could fracture without the U.S. as a key pillar. Smaller European countries, feeling vulnerable without the American shield, might push for greater integration or look for alternative alliances, potentially with Russia or China, which could shift the global balance of power.

  
  

4. Reaching Out for New Alliances

In the event that Europe could no longer count on the U.S. for defense, European nations might begin seeking out new strategic alliances to fill the security vacuum. Some options include:

• Strengthening Ties with Russia or China: While unlikely to form close military alliances, some European countries might seek to forge new economic or security relationships with Russia or China to counterbalance U.S. influence. This would be controversial, however, and could lead to a major realignment in global geopolitics.

• Increased Reliance on the United Nations (UN): Europe may turn more toward the UN for peacekeeping operations and conflict mediation, although the UN's capacity to project military power is limited compared to NATO.

• Bilateral Partnerships with Other Global Powers: Some European countries could strengthen military and economic cooperation with countries like India, Japan, or Australia, who share concerns about global stability, even though these nations are geographically distant.

  
  

5. A More Divided World

The end of U.S. military support for Europe would lead to a world where military power is more decentralized, and countries would need to rely more on their own capabilities or regional security pacts. This could give rise to more regional conflicts as global powers like Russia and China assert their influence, leading to a potentially more fragmented and unstable international order.

Furthermore, the strategic importance of Europe could diminish as other global regions, such as the Asia-Pacific, become the focal point for U.S. military and economic engagement. This could cause Europe to lose its leverage in global diplomacy and trade, relegating it to a more passive role on the world stage.

Conclusion

If Europe could no longer rely on the United States for military support, the consequences would be profound. From weakened security and increased vulnerability to the need for enhanced military autonomy, Europe would face numerous challenges in adapting to a new geopolitical landscape. The loss of U.S. military backing would not only strain European resources but could also disrupt the continent's economic stability and political cohesion. In such a scenario, Europe would need to rethink its defense and diplomatic strategies and could find itself forging new alliances while navigating a more volatile and uncertain world.
